TROLLEY.

Specification of Letters Patent. Application filed May 1, 1913.

Patented Dec. 30, 1913. Serial No. 764,920. (ModeL) To all whom it mayconcern Be it known that I, PETER JoHNsoN, a Subject of the Czar ofRussia, residing at Heaton, in the county of McKinley and State of NewMexico, have invented certain new and useful Improvements in Trolleys,of which the following is a specification, reference being had thereinto the accomaanying drawing.

This invention relates to trolleys, and the primary object of myinvention is to furnish a trolley harp with novel spaced apart guardsthat are arranged to prevent accidental displacement of a trolley wheelrelatively to a trolley wire, or other electric conductor, particularlywhen the Wheel passes around a curved section of trolley wire orencounters irregularities in the same.

Another object of this invention is to provide a guard for trolleywheels that can be used in connection with the present type of trolleyharp and without interfering with frogs, guard rails, hangers or otheroverhead fixtures.

A further object of this invention is to provide a trolley consisting ofcomparatively few parts that are inexpensive to manufacture, easy toassemble, durable and highly eiiicient for the purposes for which theyare intended.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a sideelevation of a trolley in accordance with this invention, and Fig. 2 isa plan of the same.

Further describing the invent-ion in detail with reference to theaccompanying drawing, wherein like numerals denote corresponding partsthroughout: 1 denotes a portion of a trolley pole having a harp 2 andrevolubly mounted in said harp by a transverse journal pin 3 is atrolley wheel 4 adapted to travel against a trolley wire 5.

The reference numeral 6 denotes vertical parallel guard mounted upon thepin 3, between the arms of the harp 2 and the wheel l. These plates havethe forward ends thereof beveled, as at 7 whereby should they encounteroverhead fixtures, said plates can readily ride plates that arepivotally under the same without injury to said fiX- tures. The plates 6are spaced apart by rectangular blocks 8 and 9 having reduced oval ends10 extending through said plates, the reduced oval ends of said blockspre venting the blocks from rotating between said plates. The reducedends of the block 8 are provided with cotter pins 11 and connected tothe reduced ends of the block 9 are the upper convolutions 12 of coiledsprings 13, said springs having the lower convolutions thereof connectedto a transverse pin 14- mounted in a web 15, carried by the underneathside of the pole 1. The guard plates 6 provide oppositely disposedparallel walls atthe sides of the trolley wheel 4 and these walls areadapted to prevent the wire 5 from entirely leaving the harp. Should thewheel 4 become displaced the guard plates will retain the wire 5 inposition whereby the wheel can readily ride into engagement with thesame, and the springs 13 maintain the guard plates horizontal relativelyto the wire 5 but permit of said plates assuming an angle should anobstruction be encountered.

One embodiment of the invention has been illustrated, but it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaim.

What I claim is In a trolley, the combination with a pole having a harp,a journal pin and a trolley wheel, of vertical parallel guard platespivotally mounted upon said journal pin at the sides of said wheel andwithin the harp, said guard plates having the forward ends thereofbeveled, spacer blocks arranged between said guard plates and havingreduced oval ends extending through said plates to prevent said blocksfrom rotating, one of the said blocks arranged forwardly of the other,cotter pins arranged in the ends of said rear block, and inclined coiledsprings connected to the ends of the other of said blocks and to saidpole for supporting said plates in a normally horizontal position.

In testimony whereof I afiix my signature in the presence of twowitnesses.

PETER JOHNSON.
